tried using windows update get error message 0x8024001D?

Answer 1

The virus forum is more appropriate for this,but...
you could try this

You can edit the entries that TeaTimer uses to automatically "Allow" or "Deny" changes that were based on the use of "Remember this decision" as follows:Right click on the TeaTimer system tray icon and select Settings. This will bring up TeaTimer's "White & Black List". There are four (4) Buttons across the top of the "White & Black List":
Allowed processes
Blocked processes
Allowed registry changes
Blocked registry changes


You can review all the entries that you have stored by clicking on these buttons. The entries that you should review are in "Allowed registry changes" and "Blocked registry changes". You can delete entries by clicking on the scripted black "X" to the right of the entry that you want to delete and then clicking the "OK" button when you're done. This will in effect make TeaTimer forget what you told it to remember so that during future changes to these items TeaTimer will issue a pop-up dialog rather then just a notification pop-up.
